.To all whom it may concern: 1

Be it known that I, CHARLES CEoMPToN, of Worcester, county of Worcester,State of Massachusetts, have invented an Improvement in Looms forVeaving Cane, of which the following description, in connection with theaccompanying drawings, is a specification, like let' ters and figures onthe drawings representing like parts.

This invention has for its object the production of a loom for theautomatic manufacture of fabric having warp and weft cross.- ing one theother and also having diagonal warp, my novel loom being adapted, amongother things, to the Weaving of that class of fabric employed for chairand other seats wherein cane and similar stiff material is used, theconstruction and operation of the parts being such that the naturalhardened shell of the cane may be presented always at one side of thefabric being produced; but it will be understood that I may, in my novelloom, use warp and weft and diagonal warp of any usual or suitablematerials, that depending upon the fabric which it is desired toproduce.

My improved loom contains a plurality of tracks, one or more of them,preferably all of them, having an up-and-down movement and havingloosely mounted upon them a series of diagonal warp -carriers,represented as spools or disks provided with needles or tubes throughwhich the diagonal warps are led independently into the fabric. Thesediagonal warp-carriers are free to be slid along said tracks step bystep from one to the other side of the loom or the fabric being woventherein, the movement being effected by suitable pushers to bedescribed, so that a diagonal warp wound upon a warp-carrier may beinserted at one pick at or near one selvage and then be moved laterallyto insert its thread at a subsequent pick at a point farther from theselvage of the fabric, and so on across the fabric.

It will be understood that the carriers having the diagonal warp whichare movedacross the loom in one direction in weaving must, in order tomake a uniform fabric, travel back across the loom in the oppositedirection, and to do this the carriers are made to travel in onedirectionon one track and back on another track, and in the form inwhich I have chosen to illustrate my invention one of the tracks isabove and another track below the main or body warp of the fabric; butmy invention would be useful and practical for the production of someclasses of fabric if the tracks were all in substantially the samehorizontal plane rather than in different horizontal planes.

To enable me to take the carriers intermittingly from one to the othertrack, however relatively located, I have devised a transferrer uponwhich said carriers maybe placed one after another at the proper timesor in an established order, by a pick-off to be described, and saidtransferrer-it having received a carrier-isthen moved to place thecarrier just deposited upon it, opposite the end of the other track uponwhich the carrier is to be applied preparatory to traversing the -loomor fabric in the opposite direction, the

carrier being removed from the transferrer by a pusher, there being apick-off and a pusher for each transferrer, as will be hereinafterdescribed.

In the form in which I have chosen to illustrate my invention-it beingsupposed that the spool of the carrier is supplied with a diagonal warphaving a glazed face, as is the case when cane is used-it is obviousthat the said face must beV presented always at the same side af thefabric-as, for instance, the face of the fabric-`and to provide for thisI have devised mechanism whereby the carrier, in moving from above thebodywarps into posit-ion below the body-warps, is made toA travelthrough an arc of about one hundred and eighty degrees, and when thecarrier goes from the lower to the upper track it is moved back in thesame arc, but at the opposite edge of the fabric, instead of rotating ina complete circle.

To insure the most compact arrangement of the working parts and toenable the weftinserter or needle employed to introduce the lling orweft to work closely into the shed and close to the tubes of thecarriers, I have devised means whereby the transferrer used to take acarrier from the upper and put it opposite the lower track is moved forabout ninety degrees at each step, while the transferrcr at that side ofthe loom where the needle referred to enters the shed is moved twice asfast and through an are of one hundred and eighty degrees substantiallyat each. step. The carriers are mounted loosely side by side on thetrack and are more orless in number, according to the width or characterof the fabric; and to provide for sliding the entire series of carriersalong the track, in order that the strands contained by the carriers maybe laid diagonally, I have devised means for imparting such movement tothe pusher that it acts not only to move a carrier from. a transferreronto a track, but also to move the entire series of carriers on thetrack when the tubes or needles thereof are unobstructed by body-warps,thus shifting the entire series oi' carriers for a suitable distance,according to the fabric being woven, and, as I have herein illustratedmy invention, the lateral shifting of the carriers is eicctcd on theuppermost track while the latter is in or about in its elevatedposition, said pusher leaving the endmost carrier acted directly upon byit sufficiently distant from the receiving end of said track to affordample space for the reception of the next earrier which it is desired toput onto said track, said carrier being brought by a transilerreropposite the receiving end of said track.

In the form in which I have herein illustrated my invention I haveutilized one and the same pusher, as stated, to not only shift theentire series of carriers on the track, but also to put a carrier from atransferrer onto said track; but my invention is not in this particularnecessarily limited to the use of one and the same pusher, as it will beobvious to one skilled in the art that other pusher contrivances mightbe devised for pushing a carrier from a transferrer onto a track and lorpushing the entire series of carriers on the track with but the exerciseof mechanical rather than inventive skill.

In the loom to be herein described the transferrer located at that sideof the loom opposite where the weft-inserter or needle enters the shedhas, as stated, a movement substantially one-half slower than thetransferrer at the other side, and l have chosen to divide its movementlinto two steps, there being a dwell at about ninety degrees, and duringthe iirst of said steps the transfcrrer at that side of the loom wherethe weft-needle enters the shed has imparted to it a movement over itsone hundred and eighty degrees, it then remaining stationary while theother carrier completes its second step.

The peculiar but not absolutely necessary timing referred to enables meto use the pusher not only to shift laterally the series of carriers, asdescribed,but also to put a carrier onto the track and the auxiliarypusher at the other side of the loom is also made to perform a like dutyin connection with the other track, not only to move the series ofcarriers bodily on the other track, but also to push a carrier from theauxiliary transferrer onto said track. The movements of the pushers topush a carrier from a transferrer onto a track will preferably be oi'such extent as to put the carrier on the track without neces sarilydisplacing any oi. the carriers already on the track. To certainly takethe carriers, one after another, from one end of the track and put themonto the transferrers, I have devised a pick-oit which, in this presentform oi my invention, is iliade as a magnet, said pick-oit being made atthe proper times to engage one of the carriers and, having engaged thesaine, be moved away from the track to thus pick or pull oil therefrom acarrier and put it onto a transferrer, by which it is moved next the endof another track. These magnets will preferably be of soft ironconnected in electric circuit so as to be cxcited when they are toengage a carrier and put it onto a transferrer. I have also devised whatI may designate as a mesh-gage, it serving to gage the size of the openspaces or meshes of the fabric, said mesh-gage consisting, essentially,of a bar having a series of pins to enter the spaces between the warpsvacated by the reed, and remain there while the shed is formed and forone or more picks, preferably two picks, or while the lilling is beinglaid to make the other side of a row of meshes or openings.

The reed employed by me consists, essentially, of a bar having a seriesot' strong upright pins, the free ends of which, as the reed goesforward to beat in the :filling or wei't, rises between the warps, boththe body-warps and the diagonal warps.

Duringalternate forward movements oi.' the lay to beat in the filling orweft the carriers are shifted laterally upon their tracks and the nextshed is formed, the lateral movement of the carriers causin gthediagonal warps carried by them to be laid or placed diagonally acrossthe spaces between the adjacent bodywarps, thus closing the path throughwhich the pins oi? the reed moved when the latter was driven forward tothe breast-beam. (lwing to this diagonal position ot some olf the warps,as above stated, it will be obvious that the pins oli' the reed cannotbe moved back in exactly the' same path, so I have devised means wherebythe reed, it having beaten in the filling or weft, maybe dropped orlowered at alternate picks, so that the upper ends oli its pins may bewithdrawn completely l'rom between the warps preparatory to and whilethe reed is being moved backward or away from the fell, it being raisedagain between the warps, as it is again to go forward to beat theiilling or weft into the fabric.

The movement of a reed into the warp spaces and then completely outVfrom said warp spaces, whether at alternate or at every pick, is animportant element ot' my invention.

The upward and downward movement oll the tracks on which the carriersare made to slide laterally enables the ends of the tubes or needles ofthe carriers to place the diagonal warps above or below the plane of theTOO IIO

IFS

body-warps at the proper times, so as to form between the saiddiagonalwarps and bodywarps proper sheds for the passage of the weft inserter orneedle employed to insert the filling or weft in the shed. l have alsocombined with the weft-inserter, when made as a needle, a cuttingmechanism, which severs the weftstrand, which may be of cane, betweenthe edge of the fabric and the end of the needle after the latter hasbeen retracted from the shed,the said needle during its retraction fromthe shed sliding along the weft-strand held at the opposite edge of thefabric by a suitable clamp. If the weft should not be cut off, asstated, it would have to be inserted double into the shed, which is notdesirable with cane and the like stiff weftstrand. Cutting theweft-strand off uniformly distant from the end of the needle alsoenables just the proper amount of weft-strand protruding from the end ofthe needle to be grasped by the weft clamp or catcher at the edge of thefabric opposite that at which the needle enters the shed; but in case aspun filling should be used this cutting mechanism would be omitted, andthe catcher might be of any known kind, such as usually employed inconnection with looms using a needle for the insertion of filling orweft-eas, for instance, as in looms for weaving tufted carpets and thelike. l l

This invention is not limited to any particular number of sets of tracksand carriers mounted thereon or the number of tubes or guides connect-edwith each carrier, as that may depend upon the particular pattern orclass of fabric to be woven. Nor is the invention to be hereinafterdescribed limited to the particular devices herein to be shown foractuating the essential parts hereinbefore briefly defined, as saidactuating means may be varied within the skill of a mechanic and withoutthe exercise of invention.

Different patterns ofv open-meshed and other fabrics may be woven by theemployment of carriers having the capacity of supplying diagonal warpsof different character, or by locking the differing diagonal warps intothe fabric at desired distances apart and in desired orders.

Prior to my invention I am not aware that a loom has ever been providedwith a series of warp-carrying spools which are adapted to be movedacross the fabric being woven step by step along one track and thenreturned automatically along another track, or returned in any manneralong a track.

Having described the position occupied by my invention with relation tothe state of the art and believing my invention to be a broad one, theparticular features claimed by me will be hereinafter more fullydescribed in the specification to follow, and in the claims at the endthereof.v

most of the tubes on said figures being, however, shortened to avoidcrowding the drawing. Fig. E25 shows a few body and diagonalwarp-threads united by a weft to make a cane fabric. Fig. 2G is anenlarged detail of the weft-detainer or clamp.

The loom-frame A is and may be of suitable shape to sustain the workingparts. The frame has bearings for a suitable power-shaft A, (see Fig.10,) provided with any usual or suitable driving-pulley under thecontrol of a suitable shipper or device, whereby the loom may be startedor stopped, as desired. rllhe power-shaft has a pinion A2, which engagesa tooth-gear A3, fast on the main or cani shaft A4, said cam-shaft beingprovided as represented, with a tooth-gear A5, which acts upon anintermediate pinion A(1 and rotates a bevel-bear A1, which in turnengages a bevelgear AS, mounted en a short shaft A1,sup ported insuitable bearings in a stand A1, connected with the loom-frame, saidshaft having an arm A12, to which is suitably connected a link A13, inturn jointed (see Fig. 11) te an arm A1, pivoted at A15 on a stand A1,said arm A11 having a bearing at its upper end for the reception of astud A17, on which is mounted to turn a hub connected to the upper endof a casting A13, mounted to turn on the pivot A15, and shaped to havebolted to it by bolts (300, and thus constitute a holder for the lowerend of the lever A1", the upper end of said lever being attached by alink A2U to a carriage A21, to which, in this instance of my invention,is attached one end of the weft inserter or needle A22, used tointroduce the weft, said inserter or needle being represented as hollowand as adapted to slide in a guide A23. The carriage A21 runs freely ona rod B, fixed with relation to the framework, the carriage beingprevented from overturning by entering a slot (shown best in Fig. 1) inguide B. The inner end of the weft-inserter is also, in this instance ofmy invention, made to work through a hole in a bleek B1, (see Figs. 1,12, and 13), said bleek also forming one member of a weft-cuttingmechanism, the other member thereof consistin g of a blade or device B3,represented as pivoted and as connected by a red B'1 with a slide B5,mounted on a guide B, said slide being normally elevated, in thisinstance of nry invention, by a contractile spring B7, the said slidebeing adapted to be depressed at the proper time to actuate the cutterand eut off the filling, as will be described, by the aetion of a pinB3, which may be carried by the link A13 before described, said pinacting on a projecting part or shelf B51j of the slide Bi'.v

The weft inserter or needle herein shown has at its inner end (see Fig.14:) a pivoted dog B11, which is acted upon by a suitable spring B111,so that said dog engages the weft or filling led through said needle,and acts to carry the same positively with it into the shed, such dog orsome equivalent device being nceessary, especially when the filling isof a stiff or slippery material like cane or wire. This invention isnot, however, limited to the particular construction shown for thefilling-inserter, nor to the means for actuating it, as it may deriveits motion in various ways and produce the same result, and instead ofthe particular filling-inserter I may use any other usual or suitablefilling-inserter adapted, for instance, te insert a textile or spunfilling, as in weaving of textile fabrics.

Suitably supported upon the loom above and back beyond the guide B',(see Figs. 1, 2, 3, 1411, and 140,) is a bearing B12, which receives theshaft B13 of the transferrer B11, said transferrer having two arms fromwhich. project wings 10 and 12. The head of the transferrer B1A1 (seeFigs. 3 and 11C) has two notches 13, and the shaft of the transferrerhas fast upon it a tooth-gear 14, (see Figs. 1, 2, 111, and 18,) whichis engaged and rotated at proper times by a train of gears (sce dottedlines, Fig. 3) composed of a gear 15, a pinion 16, engaged by a pinion17, fast on a gear 18, driven by a pinion 1f), splined on a shaft 20, and having an annularly-grooved hub embraced by the forked end of a lever21, mounted on a stud 22, and havingat its rear end a suitable roller orother stud which enters the groove Vin the cam-hub 23, fast on shaft A1,so as to slide gear 19 into and out of engagement at regular intervalswith relation te gear 1S. The shaft of the transferrer B1'1 is thusrotated intermittingly by the gears referred to at the proper times, andits wings 10 'l2 must be iliade to stand evenly and squarely withrelation to the tracks t t to be described, and to aid in positioningthese wings accurately I have provided the leem with a locking device25, (see Fig. 3,) composed, as herein represented, of a lever having aroll, a spring 2G acting on the lever causing said roll. to ride on ahub of the transferrer and enter one of the two notches 13 thereof (seeFig. 11") as seen as the wings of said transferrer arrive in alignmentwith the tracks.

Each transferrei.' will in practice have a like locking device. Insteadof the particular locking device shown, I may employ any otherequivalent device.

The diagonal warp-carrier (see Fig. 1.11) is composed, essentially, of abody part on., grooved to fit and slide on a traekt or t', said bodyhaving arms m fm1", between which is mounted a spool or disk-bobbin mlonwh ich is wound the diagonal weft, said weft bein g either cane,wire, orfibrous material, and a needle or tube m1,having a suitable delivery-eyefnr" for the diagonal warp. As shown in Figs. 1 ,2,and 14", the spoolorbebbin is very thin and its side walls are separated about the widthof the cane, and the journals of the spool projected from each endthereof enter notches in the arms m m2, as shown. in Fig. 17, they beingpreferably spring-arms to bear against the spool and by their frictionprevent the too rapid or easy rotation thereof. The notches in thebodies of the carriers are shown as of IOO ISO

dovetail shape in cross-section, and the tracksv herein shown, anelectromagnet h3, providedl with an extended pole-piece h4, which isadapted to engage a portion of one of the diagonal warp-carriers m,preferably its body, the magnet, it having been excited, engaging andpulling the carrier from the lowermost track t and putting it upon thatwing of the transferrer B14, then opposite it, the pick-off during suchoperation being moved positively7 by suitable actuating mechanism,herein represented as a lever h5, mounted on a stud h6 of the stand h,said lever at its upper end being slotted to embrace a stud h, .projected from the shank h2, the opposite end of said lever having jointedto it a rod hs, in turn attached to one arm of a rocker-shaft hg, havingits rearwardly-extended arm provided with aroller or other stud 7h10,which bears upon a cam h12,(see Fig.l0,) fast on the main shaft A4. `Themagnet referred to is in an electric circuit on wires 71.13 7t14, thefinger 71,15 connected with the wire h13 making electrical connectionwith the metal plate hm, carried by the shank of the magnet, so thatwhen the magnet is thrown back out of working position the circuit willVbe broken, and when in;

position to engage a part of a diagonal warpcarrier and pull it off atrack the circuit will be closed.

Going now to the opposite side of the loom, Jthe loom side has a standC, (see Fig. 2,) which receives a stud l 30, upon which is mounted anelbow-lever Cf, one arm of which is slotted to embrace a pin on theauxiliary pusher C2, represented as a bar adapted to slide in a bearingC3, xed to said stand, the inner end of said pusher being shapedsubstantially as shown in Figs. 2 and2, to act upon a part of one of thediagonal warp-carriers, as in Figs. 2O and 2l, and push it from thelowermost wing of the transferrer C4, located at that sideof theloomfand put the said carrier onto the lowermost track t at the desiredtime, and also to act a second time, as represented in Figs. 1S and 19,where the tracks t t are separated to meet the endmost carrier on thetrack i, and push or feed the entire series of carriers along on thesaid track in order that at the next shed the said carriers may put thediagonal warps carried by them into the fabric a little farther distantfrom the edge of the fabric from which the said carrier is traveling.

The transferrer C4 at the left-hand side of the loom is just like thetransferrer B14 atthe right-hand side of theloom and before described,so I have omitted it from Fig. l, but I have shown in place the piniona4 on its shaft, which pinion is rotated by a train of gearing slightlydifferent from that for moving pinion 14 on transferrer B14, there beingone less gear in the train for driving transferrer C4, said gears beingalso of a different size, so that said transferrer C4 has imparted to itnot only a slower motion, but amotion in the opposite direction fromthat of the transferrer B14.

The direction of rotation of the transferrer C4 is such as to take acarrier from the upper track t and carry it back and down to the lowertrack in substantially two steps of about ninety degrees each; but thedirection of rotation of the transferrer B14 is such as to take acarrier from the lower track t and move backwardly and upwardly to theupper track, and the transferrer B14 turns through an arc ofsubstantiaily one hundred and eighty degrees, while the transferrer C4travels through an arc of substantially ninety degrecs.

The transferrer B14 takes a carrier from the lower track and carries itby a quick motion to the upper track and then rests while theweftinserter enters and retires from the shed7 and when the transferrerB14 rests the transferrer C4 is completing the second half of itsmovement.

Referring to Fig. 2, the shaft 2O has fast on it a pinion d, whichengages a toothed gear a', the hub of which has a pinion a2, whichengages a gear a3, which in turn engages the gear a4, fast on the shaftof the transferrer C4. By working the transferrers in oppositedirections, as stated, or down in the rear half of a circle and up againin the same half of the circle at the opposite ends of the tracks it ispossible to keep the same natural hardcoated face of a strand ofdiagonal warp uppermost whether the same is being introduced into thefabric from the upper side or from the lower side of the body orstanding warps.

The shaft A4 has fast upon it a dwell-gear D, it being hereinrepresented as provided with two segmental series or sets of teeth, (seeFigs. 10 and 101,) each extended for about ninety degrees about itsperiphery and about ninety degrees apart, the said gear having extendedlaterally from it opposite its blank spaces segmental flanges DX, whichare acted upon intermittingly by a locking projection D', connected to apinion D2, having preferably one of its teeth removed, so that saiddwell-gear may rotate said pinion intermittingly, said pinion in thepresent embodiment of my invention being rotated once and then left atrest until again to be rotated. The pinion D2 is fast on a short shaftD3, having a bevel-gear D4, which engages a bevelgear D5on a shaftD6,having a second bevelgear D7, engaging a bevel-gear D8 on a shaft D9,said shaft having a bevel-gear D10, which IOO IIO

engages a bevel-gear D12, fast on and to rotate the shaft 20, beforedescribed, the said shaftbein g thus rotated intermittingly twice with adwell between each rotation, while the gear D on shaft A4 is rotatedonce;

The pick-off b, (see Fig. 2,) located at the leftshand side of the loomis also, as I have herein chosen to 'represent my invention, made as amagnet having a pole-piece Z2, which in the reciprocation of thatpick-off is adapted to engage part of a diagonal warpcarrier and pullthe same from the upper track t', as described, of the pick-off at theright-hand side of the looln upon that wing of the transferrer C4 thenopposite the end of that track, both tran sferrers being stationaryduring the operat-ion of the piek-off. The shank bcl of the pick-oitextended through a suitable guide b2, (see Figs. 1 and 2,) is providedwith a suitable pin or projection, which is engaged by a bell-cranklever b3, pivoted at 7), said bell-crank lever being joined by a rod If(see Fig. 1) with a lever DG, (see Figs. l, 7, and 10,) adapted to beactuated by a cam 117, fast on the main shaft A4, a suitable spring 31(see Fig. 1) serving to keep a roller or other stud of the said lever incontactwith the said cam, the outer end of the shank DX being shown inFig. 10 as slotted to straddle the shaft D9, the latter preventing thesaid shank from rotation. Immediately behind the cam 07 is a cam lr,(see Fig. 10,) which actuates a lever b", joined to a link blo, (seeFig. 2,) which link is connected to and moves the elbow-lever C', whichaetuates the pusher C2, before described.. The main shaft has twosuitable cams d (W, (shown best in Figs. 0 and 10,) which actuateharness or treadle levers d. cl3, joined in usual manner at theirforward ends by rods or other suitable connections (14d/l with the undersides of heddleframes d (Z7, (shown best in Fig. 2,) each frame beingprovided with suitable heddles (ZS, having eyes for the reception of themain longitudinal or body warp-threzuls w', which may come into saidheddle-cyes from any suitable source, according to the material beingused for the main or body warp-as, for instance, if cane is being wovenand that material is used for the body-warp, it will be taken into theloom under suitable tension devices (Zw, which may be as represented inFig, 1 and in the detail Figs. 9 and 9", where they are shown as platesacted upon by springs, one plate for each warp-strand, so that thetension may be kept uniform thereon.

In either instance I pre-' partially broken oit in Fig. 2,) said link atits upper end entering a guide c", the link having a block c5 attachedto it in an adjustable manner by a bolt, said block having connected toit a link el, which is jointed to what I have chosento call the mainpusher c, mounted on a pivot e7 at the lower end of a yoke e8, thelatter having arranged within it an eccentric e, fast on a shaft c. Aroll at the end of the lever c is held in contact with the cam e by asuitable spring c2, Fi 7, and when the link c3 is pulled down the saidpusherthe shaft c18 being then at rest with the eccentric down-willthrow the lower end of the pusher e toward the centerof the loom or inthe direction of the arrow thereon, (see Fig. 23,) and at that time thepusher will act on a carrier, then on a transferrer lil", and will pushit onto the track t', and thereafter, as the loom continues to run, theshaft e18 inits rotation will lift the yoke and the link el" bein g thenstationary the said pusher will be given a second movement toward thecenter ol. the loom, said movement being preferably, however, inereasedsomewhat by the cam c, which continues in rotation, it having an extraprojection 20-1to act at that time, it at that time acting against theendmost carrier m of the series of carriers already on the track t',(see Figs. 21 and 18,) and pushing the entire series of carriers alongsaid track, leaving a space (see Figs. 20 and 21) for the next carrierto come onto the track from the transferrcrl11 at another operation ofthe pusher. The shaft 618, rotated through the attached bevelgear DI,engaged by bevel-gear Dl5 on shaft D9, has two like cams f, which enteropenings in the trackearryin g yokesj", having shanks f2 fitted to slidein suitable guides f, the lower ends of said yokes carrying the uppertra-ck t for the diagonal strand or warp-carriers, the lower track tbeing carried by the upper ends of two like track-earrying yokes f,(shown in Figs. 2 and 0,) they being raised and lowered at the propertimes by cams f5 on the shaft 20. As these yokes are made to approacheach other, they carry the needles or tubes of the diagonal warp orstrand earriers past each other vertically in such manner as to crosssaid warps to form between them a shed for the weft-inserter, and theyalso carry the diagonal warp or strands above and below the plane of thebody-warpsbeing used. The wings at the opposite ends of each transferrerare distant from each other just the distance between the tracks t t\Vhen the filling-inserter with its filling w is workin in the shed andwhen the tracks are nearest together, the pick-offs will be moved toengage the diagonal warp-carriers nearest them, and then occupying aposition at the extreme ends of the track will pull said carriers fromthe tracks onto a wing of the transterrer.

rlhe shaft 20 (see Figs. 2 and has an attached sproeket-wheel g, which.by a sprocketchain g', passed over a sprocket-wheel on a shaft g,rotates said shaft whenever' shaft- IOO ITO

2O is rotated through the dwell-gear D. Theshaft Q3 has mounted on it,loosely, levers Q1, having the lower sides of their hubs (see Figs. 2and 4) connected by an eccentric-strap Q5, encircling an eccentric QG onshaft 20, said eccentric-strap vibrating said levers about shaft Q3. Thelevers have guides in which are inserted the legs Q7, carrying thelay-bar QS, having erected on it the pins or studs Q2, constituting thedents of the reed, the lower ends of said legs having rolls Q10, whichrun on cams Q12 fast on the shaft Q3. The rocking of the levers Q4effect the backward and forward movement of the lay, while the cams Q12effect the up-and-down movement thereof to enable the reed-dents to bein proper position to beat up the filling as the lay is moved forwardand to enable the lay to be dropped on its backward movementsuiiiciently to lower the reed from the spaces between the body-warps toenable it to pass under the diagonal warps when laid across said spaces.Suitable springs 41, (see Figs. 1 and 2,) shown as connected to said layand the hub of lever Q1, act normally to keep the rolls Q10 on the camsQ12. The cross-girth B12X in this instance, sustains a stand u, providedwith a stud u, on which is pivoted the filling-clamp, (shown in Figs. 1and 7 and enlarged in Fig. 26,) composed, as herein represented,essentially of two elbow-levers u2 as, faced preferably withindia-rubber, said elbow-levers having jointed to them links 44 45,attached, preferably, by one pin to a rod u1', attached to one arm of arocker-lever a7, acted upon by cam u8, said clamp being opened at theproper time to let -the end of the filling inserter or needle passbetween them, the clamp being then closed to-clasp the end of the illingw projected from the end of the inserter, thus holding said fillingwhile the carrier is retracted.

I will designate in Figs. 1S to 24 the righthand pick-off bythe letterH.

In order to illustrate the operation of my improved loom in weaving, Iwill refer to the diagrams, Figs. 1S to 24, inclusive, wherein I haveshown portions of the two tracks, the uppermost track being supposed tobe nearest the .breast-beam, and in said figures I have shown parts ofthe transferers, and parts of the pull-offs, and in connection withFigs. 1S, 19, 22, 23, and 24 I have shown in detached views the relativepositions of the transferrers.

Referring now to Fig. 1S, where the tracks are fully separated, it willbe seen that the two wings of the transferrcr B11 occupy positions oneabove and the other below the line of travel of the weft-inserter, andthat the pusher c6 has acted to push the series of carriers along uponthe upper track to provide for inserting the diagonal warps supposed tobe carried thereby each in its proper place in the warps, for it will beremembered that these carriers travel intermittingly from one to theother end of the tracks and are to insert the warps carried by them intodifferent portions of the fabric being woven from selvage to selvagediagonally. The pusher e, in addition to moving all these carrierssimultaneously along the track, also acts to push the endmost carrierneXt to it far enough on the track t to leave a space sufficient so thatwhen the next carrier comes onto the track it will ind an ample spacefor its reception, and so that at that time the pusher shall not have adouble duty to perform-that is, the duty of removing a carrier from atransferrer onto the track and also at the same time moving all thecarriers-but this mightl be done if desired, and yet be with the scopeof my invention. In Fig. 18 the pusher eG is supposed to have finishedits movement to the left and as just starting in its movement to theright in the direction of the arrow thereon. Going to the right-handside of the figure, the pick-off His supposed to be standing still, andthe pusher C's as just starting to move in the direction of the arrownear it, and the transferrer C2 is supposed to be coming down in thedirection of the arrow, it having upon one of its wings a carrierpreviously taken from the track f.

In Fig. 19 the tracks have, it will be supposed, been started towardcach other, the pick-oif II remains stationary, and the carrier m hasmoved yet a little farther, but the pusher C2 has moved quickly forward,has struck the endmost carrier of the track t', and has moved the entireseries of carriers along said track from the position Fig. 18 into theposition Fig. 19, and has left a space at the left-hand end of the lowertrack for the reception of the carrier then hanging on the transferrerC4 at the next operation of the said pusher, while at the right-handside of the track t the endmost carrier is substantially flush with theend of the track. During the change of position from Figs. 18 to 19 theweft-inserter has started forward.

In Fig. 2O the tracks t t have been moved into their closest workingposition, the pusher c6 has completed its movement to the right, theweft-inserter has got substantially halfway into the shed, the pusher C2has been moved backwardlyin the direction of the arrow, the transferrerC1 has continued to move in the direction indicated in Fig. 19 until the`carrier on one of its wings has come opposite the end of the track t,and at the same time the pick-off II at the right-hand end of the trackt has moved to the left and come into engagement with the carrier at theright-hand end of the track.

In Fig. 2l the tracks remain in the same position as in Fig. 20, thepusher e6 is in about vits same position, the pick-off II has taken thecarrier engaged by it in Fig. 2O and pulled it onto the then lowermostwing of the transferrer B11, the pick-off b at the left-hand end of thetrack t has been moved forward from the position Fig. 20, has engaged acarrier and pulled it off the track t' onto the wing of IOO IIO

IZO

the transferrer C4, then opposite it, and the pusher C2 has been movedquickly forward from its position, Fig. 20, has struck the carrier thenheld on a wing of the transferrer C4, has moved the same from thetransferrer onto the end of the track t and onto the space left (seeFig. 20) after the operation of the pusher (represented in Fig. 19) andhas started back to the left or into its outward position, and the weftinserted has completed its stroke and is on its way back out of theshed, the weft having been suitably clamped or secured in the shed.

In Fig. 21 it will be seen that each transferrer has been provided witha carrier and each transferrer must take the carrier en it and place itopposite the other track in order that the carrier may be removed fromthe trausferrer to the track.

In Fig. 22 both transferrers have started, and the faster-movin g transferrer B"l is shown as having completed about one-quarter of arotation, and the slower-moving transferrer (1'l about one-eighth of arotation.

Between t-he positions Figs. 21 and 22 the pusher c", owing to thepeculiar construction of its devices, has a slight movement, butnot aneffective one, and it has come back into the position Fig. 22 about asthe transferrers reach the positions therein designated.

In Fig. the transferrer BH is shown as having completed its stroke ofone hundred and eighty degrees, and the weft-inserter has come quicklyinto the shed, but the transferrer C4, the slower-moving one, hascompleted about one-half of its stroke.

While the parts occupy the position in Fig. 23, the movement of thepusher ciis made in the direction of the arrow thereon in that figure tocause it to push the carrier then on the transferrer B1'l quickly ontothe upper track as represented inv Fig. 2l. The pusher e, having removedthe carrier from the transferrer B14 onto the upper track t', as in Fig.2l, the tracks are separated into the position Fig. 1S, and the shaft@18 is rotated, lifting the yoke carrying the pusher, so that the pushergets its second movement, acting' on the endnlost carrier on the track tnextit, and pushes'or feeds the entire series of carriers a-lou g saidtract, and in the meantime, between the positions Fi 2l and 1S, theweftinserter makes its full stroke and retires from the shed and thetransferrer C'l starts on its way down toward the lower track t.

From the foregoing description and an examination of the diagramsreferred to it will be readily apparent how the different earrie'rs aremade to travel across the fabric from selvage to selvage and present thewarpthreads carried by them to different pairs of body-warps, so thatthe warps or strands wound on the spools of the carriers are interlockeddiagonally across the fabric.

Fig. 25 shows a piece of cane fabric woven on my novel loom, wrepresenting the body or longitudinal warps, w/ the weft-strandsand/102, 103,104, in, w, wi, and Iws the diagonal strands. In that,figure it will be seen that the weft-straiuls fw cross the body-warp 'wover and under in pairs with a shed known as oneand-one or plainweaving, and that the diagonal warps are laid diagonally throughout saidfabric, they ruiming from one toward the other edge of the fabric and.then back again in the opposite direction, turning about a suitablewarp, as ",(.shewn at the left in Fig. 25,) which may be considered aselvage-warp. The drawings show a series of longitudinal meshes 100,101, 102, 103, 104, and 105, and in said figure it will be seei hat thediagonal warp 102 is first locked into the fabric by the pair ofweftstrands 10bI in the row 105 and that diagonal warp is again lockedinto the fabric next by the pair of weft-strands 107 in the row 104, andso on with each one, and, finally, the said diagonal warp is locked bythe pair of weft strands 111, it bein g supposed that the carrier m hascompleted its movement at that point on the track z/ and that it goesthen down under the selvage wf onto the track l. and starts across theunder side of the fabric, the laying of the diagonal warp on its returncourse being best represented by diagonal, warps w and 107.

As cane fabric has heretofore been made, the warp and weft are firstunited in to a fal )rie and thereafter the diagonal warpstrands areinserted singly through the meshes left between the warp and weft, thisoperation being performed by means of a needle actuated chiefly by hand,and each run of diagonal warp is a separate short piece. In my in,-vention, however, the diagonal warp maybe made in a long piece and woundeach onv its own spool, it being of a length to extend back and forthfrom edge to edge of the fabric, and these diagonal warps are caught ineach shed and locked by the weft-strands at each crossing thereoftogether with the body-warp, all being united into the fabric at thesame time pick after pick; or in other words, the diagonal warp-threadsare inserted and made a part of the fabric as the fabric is being builtup or woven by the weft crossing the bodyavarp, and the diagonal warp ismade to follow diagonally across the fabric, cach carrier working inproper order or sequence with different warp -threads in successivesheds. If textile filling is used the clamp will be omitted, andinstead. I shall use a shuttle or other usual device to catch thedoubled filling.

This invention i not limited to the particular construction shownfertile pick-offs or 1o making them as magnets, as I considel as withinthe scope of my invention in that par ticular any pick-olf which willtake one earrier at a time from a track and enable .it to be put onto aproper part of a transferrer to take it to another track.

This invention, as stated, is not limited to inserting the weft by onlya needle, and my ITO invention comprehends inserting the weft in theshed in any usual manner.

The loom-frame has suitable stands n (see Fig. 15) with pivots 'n' forlevers n2, having suitable rolls to rest on cams n3 on the shaft @18.The levers n2 (see Fig. 15) carry arms n4, connected rigidly bycross-bar a5, the lower ends of the arms having brackets n, whichsupportthe mesh-gage 71.7, it consisting of a bar having a series ofpins' n.8, which stand between the warps when the filling is beingintroduced back of said pins toward the center of the loom, the pinsthus gaging the size of the meshes. The pins ns rest against one edge ofthe caneY or other weft, while the reeddents giact against the otheredge thereof.

I have Vherein illustrated the tracks t t as located in differenthorizontal and also different vertical planes and the transferrers asrotatable; but this invention is not limited to the exact form oftransferrer shown or to the devices for actuating the transferrer, andbelieving myself to be the first to use a plurality of tracks on whichdiagonal warp-carriers may be slid, and from one to the other of whichthe said carriers may be automatically transferred, I consider withinthe scope of this invention any transferrer capable of taking a carrierfrom one to another track, and also any form, of pusher to co-operatewith the carriers on the transferrers of Whatever form to put them ontoa track, and also any form of pick-off to put a carrier from a trackonto a transferrer to be taken to another track.

rIhe diagonal warp-carriers may each be so shaped 'as to be engaged by alocking device p, which may be made as a spring, (see Figs.

10b and 106,) said spring having a projection to enter a notch in thecarrier, thelocking device holding under slight friction preferably thenext to the endmost carrier, so that as the series of carriers are slidon a track by a pusher, said locking device will substantially positionthat carrier or not let the series of carriers be moved farther thanactually pushed by the pusher while in contact with the carrier at theother end of the track, and, further, this locking device prevents thepickoff from taking more than one carrier.

In the modification, Fig. 17, I have shown a warp-carrier provided witha plurality of needles, so that said carrier may deliver severalwarp-threads rather than one, and said carrier may, as therein shown,have a plurality of spools. A carrier of this kind, if provided withthreads of different colors, may form a diagonal band across the fabricfrom selvage to selvage. The woven fabric, after having passed themesh-gage, is passed over the breast or feed-roll J, which may berotated at the proper speed in any usual or suitable manner, I havingherein shown said roll as having its shaft provided with a worm-v gearIl', which is engaged by a worm H2 on a vertical shaft H3.

In the drawings, Fig. l@ showing the diagonal warp-carrier on a largerscale, it will be seen that the needle is hollow and has a hole at itsend from which the warp passes into the shed, and the said warp maybeled through the needle from end to end or the warp may be led from thebobbin outside the body m and into an inlet 205, as shown by dottedlines, Fig. 145, or as in Fig. 17.

ln this present instance of my invention, wherein I have illustrated myinvention as applied to weaving cane fabric, the carriers are moved fromtrack to track and back again in the same half of a circle; but it willbe understood that this invention is not limited to moving thetransferrers only, as stated, and movement of the transferrers in anydirection to take a carrier from one to another track is within thescope of my invention, and while in this present embodient of myinvention I shift the carriers from the `tracks onto the transferrersand vice versa while the shed is closed, yet with but slight changes insome of the parts, the shifting referred to might be effected when theshed is open, so my invention is not limited to shifting the carriers atany exact position of the warps in the shed.

It will be understood in practice that the needles will be of sucientlength that when the tracks are in their closest positions the ends ofone series of tubes will pass beyond the ends of the other series, so asto cross the diagonal warp-threads and leave a space for the receptionof the filling.
